Calls in the Call Waiting Queue
The system administrator can configure and activate a call waiting queue especially for your telephone in the
Comfort Pro system. While you are making a call, new calls can be queued. These callers first hear an
announcement (if the system administrator has preset an announcement) and then the ring tone. The number
of calls permitted in the call waiting queue is set by the system administrator during system configuration,
5 calls for example. When this number is reached, further callers hear the busy tone. The calls in the queue
are put through in order of priority (baby calls, door calls, VIP calls, other internal and external calls),
irrespective of the order in which they came in.
Calls that have been in the queue for too long are removed, and the callers then hear the busy tone. The
period of time until an external call is released is set by the network operator. In Germany this is usually two
minutes and in other European countries usually three minutes.
Your telephone can have a call waiting queue even if it belongs to a subscriber group, where it simultaneously
affects call forwarding.
If several call numbers are configured for your telephone (e. g. on trunk or team keys), separate call waiting
queues are used for each number.
On the Comfort Pro P500) incoming calls are signalled by means of a short tone; they are also indicated on
the display. If there are calls in the queue, the level indicator appears at the beginning of the second line of the
Comfort Pro P500 display. If several call numbers with call waiting queues are configured for your telephone,
the total number of entries appears.
For the System Administrator:
The “Call Queue” chapter in the “Mounting and Commissioning” guide explains how to configure call waiting
queues and set up a enquiry station using this function.
